Ericsson and Qualcomm Technologies complete over-the-air 5G new radio call in recent field trial


Telecommunications firm Ericsson and multinational corporation Qualcomm Technologies have completed the first over-the-air 5G new radio (NR) call on CBRS (citizen broadband radio service) spectrum in a recent field trial.

This combination of 5G NR over CBRS will enable a wide range of new applications for enterprises and industry verticals, which in turn supports the proliferation of private networks, Qualcomm says.

“The promise of 5G NR in the CBRS band offers nearly unlimited potential for enterprise applications and industries, and we are excited to once again collaborate with Qualcomm Technologies,” says Ericsson North America vice president network product solutions Paul Challoner.

“This collaboration enables the full potential of 5G and will help address the increasing data demand and evolving use cases for wireless connectivity among consumers, enterprises, governments, and other organisations,” notes Qualcomm Technologies vice president product management Qualcomm Technologies Francesco Grilli.

“Qualcomm Technologies has since supported its Snapdragon Mobile Platforms, LTE modems, and the Snapdragon X55 and X65 5G Modem-RF Systems since 2017. We are excited to create opportunities for deployment and to enable better user experiences in a wide array of scenarios,” adds Grilli.

CBRS, shared spectrum from 3.55 to 3.7GHz, has been the catalyst for innovation to expand cellular usage beyond enhanced Mobile Broadband (eMBB) in the US.

Combined with the commercial rollout of Priority Access Licenses (PAL), LTE-based CBRS network deployments are rapidly proliferating across thousands of sites.

These sites enable use cases such as fixed wireless access (FWA), mobile network densification, and private cellular networks.

As the rollout of 5G NR network equipment in the CBRS band continues, private cellular network performance will deliver improved throughput, reduced latency, enhanced reliability, and greater connection density – thereby allowing for advanced applications such as mobile robotics, connected manufacturing and facilities, augmented reality industrial applications, according to Qualcomm.

In addition, the coordination of CBRS and licensed spectrum, such as C-band, through carrier aggregation further delivers increased capacity to enhance the user experience.

The field trial took place at Ericsson’s North America headquarters in Plano, Texas, utilising the previously announced Ericsson 5G Distributed Innovation Network together with a smartphone form-factor test device powered by Snapdragon 888 5G Mobile Platform with the Snapdragon X60 5G Modem-RF System.

The standalone 5G network configuration with rooftop radios emulated various real-life test scenarios, including intra- and inter-band mobility and carrier aggregation (3.55-3.7GHz TDD and C-band), as well as mobility between n48 and 5G low-band, or 4G.

Ericsson radios 4408 and AIR 6449 and the smartphone form-factor test device were used for this trial and the over-the-air environment was made possible with the Federal Communications Commission (FCC) test licenses in the respective bands.

Both Ericsson and Qualcomm Technologies offer a full suite of solutions to support customers on their journey as industries like manufacturing, mining, and ports look to cellular indoors for low-latency, reliability, and to support massive numbers of IoT devices.

Ericsson says it has been focused on strengthening its 5G indoor portfolio to help make it the simplest and most flexible product range on the market.

As the field trial ends, both companies say they are one step closer to 5G services on the CBRS shared spectrum.
